Description

Die Erfindung betrifft Komponententräger für Komponenten in Gondeln von Windenergieanlagen sowie eine Windenergieanlage mit einem entsprechenden Komponententräger.The invention relates to component carriers for components in nacelles of wind turbines and to a wind turbine with a corresponding component carrier.

Windenergieanlagen gemäß dem Stand der Technik umfassen in der Regel einen Rotor, der drehbar an einer Gondel angeordnet ist, wobei die Gondel wiederum drehbar auf einem Turm angeordnet ist. Der Rotor treibt über eine Rotorwelle ein Getriebe an, welches auf seiner Abtriebsseite mit einem Generator verbunden ist. Es sind auch Windenergieanlagen bekannt, bei denen der Rotor direkt, d. h. ohne ein dazwischengeschaltetes Getriebe, mit dem Generator verbunden ist. Eine durch Wind induzierte Rotationsbewegung des Rotors kann so in elektrische Energie gewandelt werden, die dann ggf. über Umrichter und/oder Transformatoren in ein elektrisches Netz eingespeist werden kann.Wind turbines according to the prior art usually comprise a rotor which is rotatably arranged on a nacelle, wherein the nacelle is in turn rotatably mounted on a tower. The rotor drives a gear via a rotor shaft, which is connected on its output side to a generator. There are also wind turbines are known in which the rotor directly, d. H. without an intermediate transmission, is connected to the generator. A rotational movement of the rotor induced by wind can thus be converted into electrical energy, which can then optionally be fed via converters and / or transformers into an electrical network.

In der Gondel ist eine Tragstruktur für die dort angeordneten Hauptkomponenten der Windenergieanlage, wie bspw. den Generator oder das Getriebe, vorgesehen. Bei dieser Tragstruktur handelt es sich häufig um eine Stahlträgerkonstruktion mit zwei in Längsrichtung der Gondel verlaufenden Hauptträgern, die durch Querträger zu einer Rahmenkonstruktion miteinander verbunden sind. Die Stahlträgerkonstruktion ist dafür ausgelegt, das hohe Gewicht des Generators und/oder des Getriebes aufzunehmen und in das Lager, um das sich die Gondel gegenüber dem Turm drehen lässt, einzuleiten. Aus der DE 10 2008 046 210 A1 ist eine Tragstruktur bekannt, bei der einzelne Träger der Stahlträgerkonstruktion über biegeweiche Bleche miteinander verbunden sind, um Spannungsspitzen in der Tragstruktur zu vermeiden. Das Dokument EP 1 715 182 A1 beschreibt eine starre Tragstruktur für den Generator einer Windenergieanlage, an welcher der Generator über Dämpfungselemente angebunden ist.In the nacelle, a support structure for the main components of the wind power plant arranged there, such as the generator or the transmission, is provided. This support structure is often a steel girder construction with two main girders extending in the longitudinal direction of the gondola, which are connected together by crossbeams to form a frame construction. The steel girder structure is designed to accommodate the high weight of the generator and / or the transmission and to introduce it into the bearing around which the gondola can be rotated relative to the tower. From the DE 10 2008 046 210 A1 a support structure is known in which individual carriers of the steel girder construction are interconnected via flexible sheets in order to stress peaks in the support structure avoid. The document EP 1 715 182 A1 describes a rigid support structure for the generator of a wind turbine to which the generator is connected via damping elements.

Um weitere Komponenten, wie bspw. Schaltschränke etc., in der Gondel anzuordnen, ist es bekannt zwischen den beiden Längsträgern der Tragstruktur noch weitere Hilfsträger anzuordnen, auf denen dann die weiteren Komponenten befestigt werden können. Die Hilfsträger werden dabei in der Regel an den Längsträgern der Tragstruktur festgeschweißt.In order to arrange further components, such as control cabinets, etc., in the nacelle, it is known to arrange further subcarriers between the two longitudinal members of the support structure, on which then the other components can be attached. The subcarriers are usually welded to the longitudinal members of the support structure.

Die Hilfsträger sind für die grundsätzliche Tragfähigkeit der Tragstruktur nicht erforderlich, werden aber bei Belastung der Tragstruktur - bspw. durch Anbringen des Generators auf der Tragstruktur - mitbelastet. Damit sich die Hilfsträger bei entsprechender Belastung nicht von der Tragstruktur lösen, müssen die Schweißverbindungen zwischen Hilfsträger und Tragstruktur hoch belastbar sein, was zu hohen Kosten führt. Trotzdem hat die Erfahrung gezeigt, dass die beschriebenen Schweißverbindungen problematisch sind und daher regelmäßig überprüft werden müssen.The subcarriers are not required for the basic load-bearing capacity of the support structure, but are loaded when the support structure is loaded, for example by attaching the generator to the support structure. So that the subcarrier does not detach from the support structure with a corresponding load, the welded joints between subcarrier and support structure must be highly resilient, which leads to high costs. Nevertheless, experience has shown that the welds described are problematic and therefore must be checked regularly.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Komponententräger für Komponenten in Gondeln von Windenergieanlagen zu schaffen, bei dem die aus dem Stand der Technik bekannten Nachteile nicht mehr oder nur noch in vermindertem Umfang auftreten.The invention is therefore based on the object to provide a component carrier for components in nacelles of wind turbines, in which the disadvantages known from the prior art no longer occur or only to a lesser extent.

Gelöst wird diese Aufgabe durch einen Komponententräger gemäß dem Hauptanspruch. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.This problem is solved by a component carrier according to the main claim. Advantageous developments are the subject of the dependent claims.

Demnach betrifft die Erfindung einen Komponententräger für Komponenten in Gondeln von Windenergieanlagen umfassend ein Trägerelement zur Befestigung der Komponenten daran und wenigstens ein biegeweiches Anbindungsblech mit jeweils zwei Anbindungspunkten zur Anbindung des Trägerelementes an einer Tragstruktur der Windenergieanlage, wobei das wenigstens eine Anbindungsblech an seinem einen Anbindungspunkt mit dem Trägerelement und an seinem anderen Anbindungspunkt mit der Tragstruktur verbindbar ist und wobei die Länge des Anbindungsbleches zwischen den beiden Anbindungspunkten größer ist als der Abstand zwischen den beiden Anbindungspunkten.Accordingly, the invention relates to a component carrier for components in nacelles of wind turbines comprising a support member for attaching the components thereto and at least one flexible soft connection plate with two connection points for connecting the support member to a support structure of the wind turbine, wherein the at least one connection plate at its one connection point with the Carrier element and at its other connection point with the support structure is connectable and wherein the length of the connection plate between the two connection points is greater than the distance between the two connection points.

Die Erfindung betrifft weiterhin eine Windenergieanlage mit einer Tragstruktur in der Gondel, wobei ein erfindungsgemäßer Komponententräger vorgesehen ist, dessen wenigstens eines Anbindungsblech mit seinem einen Anbindungspunkt mit dem Trägerelement und an seinem anderen Anbindungspunkt mit der Tragstruktur verbunden ist.The invention further relates to a wind turbine with a support structure in the nacelle, wherein a component support according to the invention is provided, whose at least one attachment plate is connected with its one connection point with the support element and at its other connection point with the support structure.

Der erfindungsgemäße Komponententräger für Komponenten in Gondeln von Windenergieanlagen umfasst neben einem Trägerelement zur Befestigung der Komponenten daran, welches an der Tragstruktur der Windenergieanlage befestigbar ist, noch wenigstens ein Anbindungsblech mit zwei Anbindungspunkten, von denen der erste mit dem Trägerelement und der zweite mit der Tragstruktur der Windenergieanlage verbindbar ist. In anderen Worten ist im Einbauzustand das Anbindungsblech zwischen Trägerelement und Tragstruktur vorgesehen, sodass die Verbindung zwischen Trägerelement und Tragstruktur im Bereich des Anbindungsblechs über eben dieses hergestellt wird.The component carrier according to the invention for components in nacelles of wind turbines comprises, in addition to a carrier element for fastening the components thereto, which can be fastened to the supporting structure of the wind energy plant, at least one connection plate with two attachment points, of which the first with the carrier element and the second with the support structure of Wind energy plant is connectable. In other words, in the installed state, the connection plate is provided between the carrier element and the support structure, so that the connection between the carrier element and the support structure in the region of the connection plate is produced via same.

Da erfindungsgemäß die Länge des Anbindungsbleches zwischen den beiden Anbindungspunkten größer ist als der Abstand zwischen den beiden Anbindungspunkten, ist festgelegt, dass die beiden Anbindungspunkte durch das Anbindungsblech nicht auf kürzestem Weg, d. h. in einer geraden Linie, miteinander verbunden sind, sondern das Anbindungsblech eben nicht gerade verläuft. Dadurch wird erreicht, dass eine gewisse Relativbewegung der beiden Anbindungspunkte zueinander möglich ist, wobei eine entsprechende Relativbewegung zu einer Biegeverformung des Anbindungsbleches führt. Im Vergleich zu den im Stand der Technik üblichen starren Verbindungen - bspw. direkte Schweißverbindungen - können durch ein erfindungsgemäßes Anbindungsblech so Spannungsspitzen im Bereich der Verbindung von Trägerelement und Tragstruktur vermieden werden. Das Anbindungsblech gewährleistet somit eine gewisse Entkopplung zwischen Trägerelement und Tragstruktur.Since, according to the invention, the length of the attachment plate between the two attachment points is greater than the distance between the two attachment points, it is determined that the two attachment points through the attachment plate are not by the shortest path, ie. H. in a straight line, are connected to each other, but the connection plate just does not run straight. This ensures that a certain relative movement of the two attachment points to each other is possible, with a corresponding relative movement leads to a bending deformation of the connection plate. In comparison to the rigid connections customary in the prior art-for example, direct welded joints-stress points in the region of the connection between the carrier element and the supporting structure can be avoided by means of a connecting plate according to the invention. The connection plate thus ensures a certain decoupling between the carrier element and the support structure.

Um Entsprechendes gewährleisten zu können, ist das Anbindungsblech biegeweich ausgestaltet. "Biegeweich" bedeutet in diesem Zusammenhang, dass sich das Anbindungsblech unter den zu erwartenden Belastungen elastisch verbiegt, ohne dass dabei die Grenze zur plastischen Verformung erreicht oder gar überschritten wird. Zu den zu erwartenden Belastungen gehören neben Gewichtsbelastungen durch die an dem Trägerelement befestigten Komponenten auch die Belastungen, die aufgrund von Verformungen, Schwingungen o. ä. der Tragstruktur oder des Trägerelements auftreten können.In order to be able to ensure the appropriate, the connection plate is flexible designed. "Bending soft" in this context means that the connecting plate elastically bends under the expected loads, without thereby reaching the limit of plastic deformation or even exceeded. In addition to weight loads by the components fastened to the carrier element, the loads to be expected also include the loads which may occur due to deformations, vibrations or the like of the carrier structure or the carrier element.

Der Begriff Anbindungspunkt im Sinne dieser Erfindung ist weit zu verstehen. Insbesondere ist der Begriff nicht auf tatsächlich punktförmige Verbindungen des Anbindungsbleches mit dem Trägerelement oder der Tragstruktur beschränkt. Auch linienförmige oder flache Verbindungen des Anbindungsbleches mit dem Trägerelement oder der Tragstruktur, wie sie bspw. bei Schweiß- oder Klebeverbindungen regelmäßig vorliegen, sind von diesem Begriff umfasst.The term connection point in the sense of this invention is to be understood as meaning. In particular, the term is not limited to actually point-shaped connections of the connection plate with the carrier element or the support structure. Also linear or flat connections of the connection plate with the Carrier element or the supporting structure, as they are regularly present, for example. In welding or adhesive joints, are covered by this term.

Das wenigstens eine Anbindungsblech ist vorzugsweise u-förmig ausgestaltet, wobei die Anbindungspunkte jeweils an einem der Schenkel des Anbindungsbleches angeordnet sind. Durch eine entsprechende Formgebung des Anbindungsbleches können zum einen gut die Gewichtsbelastungen durch die an dem Trägerelement befestigten Komponenten in die Tragstruktur eingetragen werden, zum anderen ist eine ausreichende Entkopplung von Tragstruktur und Trägerelement gewährleistet.The at least one attachment plate is preferably configured in a U-shaped manner, wherein the attachment points are respectively arranged on one of the legs of the attachment plate. By a corresponding shaping of the connection plate, on the one hand, the weight loads due to the components fastened to the carrier element can be registered in the support structure, on the other hand sufficient decoupling of the support structure and carrier element is ensured.

Vorzugsweise sind die Schenkel des u-förmigen Anbindungsblechs im Wesentlichen gleich lang, wobei weiter vorzugsweise die Anbindungspunkte auf den beiden Schenkeln auf im Wesentlichen gleicher Höhe angeordnet sind. Bei einer entsprechenden Ausgestaltung können Konstruktionsänderungen bereits bestehender oder geplanter Windenergieanlagen für die Verwendung eines erfindungsgemäßen Komponententrägers deutlich vereinfacht werden. So ist es in der Regel ausreichend, bei einem ursprünglich direkt an der Tragstruktur zu befestigendem Komponententräger wenige Dimensionen so zu ändern, dass zwischen Trägerelement und Tragstruktur ein Anbindungsblech angeordnet werden kann. Insbesondere im Falle von einer zur ursprünglich vorgesehenen Verbindung zwischen Trägerelement und Tragstruktur gleichartigen Befestigung des Anbindungsbleches am Trägerelement und Tragstruktur (bspw. Schweißen) ist eine darüber hinausgehende konstruktive Änderung am Trägerelement oder insbesondere an der Tragstruktur nicht erforderlich. Das Anbindungsblech kann dann nämlich an den Bereichen des Trägerelements oder der Tragstruktur befestigt werden, an denen bei der ursprünglichen Konstruktion eine direkte Verbindung vorgesehen war. Durch ein entsprechendes Anbindungsblech ändert sich darüber hinaus auch die relative Anordnung der auf dem Trägerelement befestigten Komponenten bspw. gegenüber direkt an der Tragstruktur befestigten Elementen nicht, sodass das Vorsehen von erfindungsgemäßen Anbindungsblechen dann grundsätzlich keine weitergehende Konstruktionsänderung hinsichtlich von Versorgungsleitungen o. ä. nach sich zieht.Preferably, the legs of the U-shaped connecting plate are substantially the same length, wherein more preferably, the connection points on the two legs are arranged at substantially the same height. In a corresponding embodiment, design changes of existing or planned wind turbines for the use of a component carrier according to the invention can be significantly simplified. Thus, it is generally sufficient to change a few dimensions in a component carrier which is originally to be fastened directly to the support structure such that a connection plate can be arranged between the support element and the support structure. In particular, in the case of a connection for the originally intended connection between the carrier element and supporting structure of the attachment plate on the support member and supporting structure (eg. Welding) is beyond design change to the support member or in particular on the support structure is not required. Namely, the attachment plate can then be attached to the areas of the support element or the support structure to which a direct connection is provided in the original construction was. In addition, the relative arrangement of the components fastened on the carrier element, for example, does not change as a result of a corresponding connecting plate. The provision of connecting plates according to the invention then generally does not entail any further structural change with regard to supply lines or the like ,

Das Trägerelement weist vorzugsweise eine ebene Anbindungsseite auf, an der die zu befestigenden Komponenten angeordnet werden können. Das Trägerelement bzw. die Anbindungsseite ist vorzugsweise rechteckig. Das Trägerelement ist bevorzugt so ausgebildet, dass es an zwei gegenüberliegenden Kanten mit jeweils einem Träger der Tragstruktur verbunden werden kann. In diesem Fall ist es grundsätzlich ausreichend, wenn an lediglich einer dieser Kanten wenigstens ein erfindungsgemäßes Anbindungsblech vorgesehen ist. Vorzugsweise sind aber an beiden genannten Kanten Anbindungsbleche vorgesehen.The carrier element preferably has a flat connection side, on which the components to be fastened can be arranged. The carrier element or the connection side is preferably rectangular. The support element is preferably designed so that it can be connected at two opposite edges, each with a support of the support structure. In this case, it is basically sufficient if at least one inventive connecting plate is provided on only one of these edges. Preferably, however, connecting plates are provided on both said edges.

Das wenigstens eine Anbindungsblech kann auf beliebige Weise mit dem Trägerelement und an der Tragstruktur der Windenergieanlage befestigt sein. Das wenigstens eine Anbindungsblech kann aber auch einstückig mit dem Trägerelement ausgebildet oder fest mit diesem verbunden sein. Es kann bspw. am Trägerelement festgeschweißt sein. Vorzugsweise ist das Anbindungsblech zum Anschweißen an dem entsprechenden Anbindungspunkt an der Tragstruktur ausgebildet.The at least one attachment plate can be fastened in any desired way to the carrier element and to the supporting structure of the wind energy plant. The at least one connection plate can also be integrally formed with the carrier element or fixedly connected thereto. It may, for example, be welded to the carrier element. Preferably, the connection plate is designed to be welded to the corresponding connection point on the support structure.

Das wenigstens eine Anbindungsblech ist vorzugsweise aus Stahl.The at least one connection plate is preferably made of steel.

Die erfindungsgemäße Windenergieanlage umfasst wenigstens einen erfindungsgemäßen Komponententräger, der an der Tragstruktur in der Gondel der Windenergieanlage befestigt ist. Zur näheren Erläuterung wird auf die obigen Ausführungen verwiesen.The wind power plant according to the invention comprises at least one component carrier according to the invention, which is fastened to the supporting structure in the nacelle of the wind energy plant. For a more detailed explanation, reference is made to the above statements.

Vorzugsweise handelt es sich bei der Tragstruktur der Windenergieanlage, an der ein erfindungsgemäßer Komponententräger befestigt ist, um den Generatorträger. Beim Generatorträger handelt es sich um eine Tragstruktur, auf der im fertig montierten Zustand der Generator angeordnet ist. Der Generatorträger kann direkt oder über eine weitere Tragstruktur mit dem Lager verbunden sein, um welches sich die Gondel auf dem Turm der Windenergieanlage drehen kann.The support structure of the wind power plant, to which a component carrier according to the invention is attached, is preferably the generator carrier. The generator carrier is a support structure on which the generator is arranged in the fully assembled state. The generator carrier can be connected directly or via a further supporting structure to the bearing, around which the nacelle can rotate on the tower of the wind turbine.

Die Erfindung wird nun anhand vorteilhafter Ausführungsformen unter Bezugnahme auf die beigefügten Zeichnungen beispielhaft beschrieben. Es zeigen:

  • Figur 1: ein Ausführungsbeispiel eines erfindungsgemäßen Komponententrägers;
  • Figur 2: eine schematische Darstellung einer erfindungsgemäßen Windenergieanlage; und
  • Figur 3: eine Detaildarstellung eines Teils der Tragstruktur der Windenergieanlage aus Figur 2.
The invention will now be described by way of example with reference to preferred embodiments with reference to the accompanying drawings. Show it:
  • FIG. 1 : an embodiment of a component carrier according to the invention;
  • FIG. 2 : a schematic representation of a wind turbine according to the invention; and
  • FIG. 3 : A detailed representation of a part of the support structure of the wind turbine FIG. 2 ,

In Figur 1 ist ein erfindungsgemäßer Komponententräger 1 dargestellt. Der Komponententräger 1 umfasst ein Trägerelement 2. Das Trägerelement 2 ist rechteckig ausgestaltet und weist eine ebene Anbindungsseite 3 auf, auf der eine oder mehrere Komponenten einer Windenergieanlage angeordnet und befestigt werden können.In FIG. 1 an inventive component carrier 1 is shown. The component carrier 1 comprises a carrier element 2. The carrier element 2 is designed rectangular and has a flat connection side 3, on which one or more components of a wind turbine can be arranged and fixed.

An zwei gegenüberliegenden Kanten des Trägerelements 2 sind jeweils biegeweiche Anbindungsbleche 4 aus Stahl angeordnet. Die Anbindungsbleche 4 sind jeweils u-förmig mit zwei im Wesentlichen gleichlangen Schenkeln 5 ausgestaltet, wobei an den beiden Schenkeln 5 jeweils ein Anbindungspunkt 6 vorgesehen ist. An dem einen Anbindungspunkt 6 ist das Anbindungsblech 4 fest mit dem Trägerelement 2 verbunden, im dargestellten Ausführungsbeispiel mit dem Trägerelement 2 verschweißt. An dem anderen Anbindungspunkt 6 ist das Anbindungsblech 4 mit einer Tragstruktur einer Windenergieanlage verbindbar. Die Anbindungspunkte 6 sind auf im Wesentlichen gleicher Höhe angeordnet.At two opposite edges of the support member 2 each bendable connection plates 4 are arranged steel. The connection plates 4 are each U-shaped with two substantially equal legs 5, wherein on the two legs 5 each have a connection point 6 is provided. At the one connection point 6, the connection plate 4 is fixedly connected to the carrier element 2, in the illustrated embodiment, welded to the carrier element 2. At the other connection point 6, the connection plate 4 can be connected to a supporting structure of a wind turbine. The connection points 6 are arranged at substantially the same height.

Durch die U-Form ist sichergestellt, dass die Länge l eines Anbindungsblechs 4 größer ist als der Abstand d der Anbindungspunkte 6 dieses Anbindungsblechs.The U-shape ensures that the length l of a connection plate 4 is greater than the distance d of the connection points 6 of this connection plate.

In Figur 2 ist schematisch eine Windenergieanlage 20 dargestellt. Die Windenergieanlage 20 umfasst einen Rotor 21, der drehbar an einer Gondel 22 angeordnet ist. Die Gondel 22 ist wiederum drehbar auf einem Turm 23 angeordnet. Der Rotor 21 treibt über die Rotorwelle 24 ein Getriebe 25 an, welches auf seiner Abtriebsseite mit einem Generator 26 verbunden ist. Eine durch Wind induzierte Rotationsbewegung des Rotors 21 kann so in elektrische Energie gewandelt werden, die dann ggf. über Umrichter und/oder Transformatoren (nicht dargestellt) in ein elektrisches Netz 27 eingespeist werden kann.In FIG. 2 schematically a wind turbine 20 is shown. The wind turbine 20 includes a rotor 21 rotatably mounted on a nacelle 22. The nacelle 22 is in turn rotatably mounted on a tower 23. The rotor 21 drives via the rotor shaft 24 to a transmission 25, which is connected on its output side with a generator 26. A rotational movement of the rotor 21 induced by wind can thus be converted into electrical energy, which can then optionally be fed into an electrical network 27 via converters and / or transformers (not shown).

Das Getriebe 25 und der Generator 26 sind auf einer Tragstruktur 10 innerhalb der Gondel 22 angeordnet, wobei die Tragstruktur 10 über ein Lager 28 drehbar gegenüber dem Turm 23 gelagert ist. Über diese Tragstruktur 10 und das Lager 28 können das hohe Gewicht des Getriebes 25 und des Generators 26, aber auch es Rotors 21 in den Turm 23 eingeleitet werden. Die eigentliche Verkleidung der Gondel 22 kann ebenfalls an der Tragstruktur 10 befestigt sein.The gear 25 and the generator 26 are arranged on a support structure 10 within the nacelle 22, wherein the support structure 10 is rotatably supported by a bearing 28 relative to the tower 23. About this support structure 10 and the bearing 28 can the high weight of the gear 25 and the generator 26, but also it rotor 21 are introduced into the tower 23. The actual fairing of the nacelle 22 may also be attached to the support structure 10.

In Figur 3 ist ein Teil 10' der Tragstruktur 10 der Windenergieanlage 20 aus Figur 2a dargestellt. Bei diesem Teil 10' der Tragstruktur 10 handelt es sich um den Generatorträger, d. h. denjenigen Teil 10' der Tragstruktur 10, der den Generator 26 der Windenergieanlage 20 aufnimmt. Daneben sind - anders als in der schematischen Figur 2 - in Figur 3 noch weitere, für die Windenergieanlage 20 wichtige Hilfskomponenten 29 dargestellt, die in der Gondel 22 angeordnet sind. Bei diesen Hilfskomponenten 29 handelt es sich bspw. um Umrichter, Schaltschränke oder Kühlaggregate.In FIG. 3 is a part 10 'of the support structure 10 of the wind turbine 20 from FIG. 2a shown. In this part 10 'of the support structure 10 is the generator support, ie that part 10' of the support structure 10, which receives the generator 26 of the wind turbine 20. In addition are - unlike in the schematic FIG. 2 - in FIG. 3 still further, important for the wind turbine 20 auxiliary components 29 shown, which are arranged in the nacelle 22. These auxiliary components 29 are, for example, converters, control cabinets or cooling units.

Der in Figur 3 dargestellte Teil 10' der Tragstruktur 10 umfasst zwei parallel verlaufende Längsträger 11 die durch Querverstrebungen 12 derart verbunden sind, dass die Tragstruktur 10 den auf sie einwirkenden Lasten - insbesondere den Gewichtslasten des Generators 26 - standhält. Ein Teil der Hilfskomponenten 29 ist direkt an der Tragstruktur 10 und insbesondere auf den Längsträgern 10 angeordnet und an diesen befestigt. Um darüber hinaus noch weitere Hilfskomponenten 29 an der Tragstruktur 10 anzuordnen, ist ein erfindungsgemäßer Komponententräger 1 - wie er bspw. in Figur 1 gezeigt ist - vorgesehen.The in FIG. 3 illustrated part 10 'of the support structure 10 comprises two parallel longitudinal members 11 which are connected by cross braces 12 such that the support structure 10, the loads acting on them - in particular the weight loads of the generator 26 - withstands. A part of the auxiliary components 29 is arranged directly on the support structure 10 and in particular on the longitudinal members 10 and secured thereto. In order to arrange even more auxiliary components 29 on the support structure 10, an inventive component carrier 1 - as it is, for example, in FIG. 1 is shown - provided.

Die weitere Hilfskomponente 29' ist auf der Anbindungsseite 3 des Trägerelements 2 angeordnet. Das Trägerelement 2 selbst ist über die u-förmigen Anbindungsbleche 4 an der Tragstruktur 10 befestigt, wobei die Anbindungsbleche 4 an den Anbindungspunkten 6, die nicht mit dem Trägerelement 2 verbunden sind, mit der Tragstruktur 10 verschweißt sind.The further auxiliary component 29 'is arranged on the connection side 3 of the carrier element 2. The carrier element 2 itself is above the U-shaped connecting plates 4 on the support structure 10, wherein the connecting plates 4 are welded to the connection points 6, which are not connected to the carrier element 2, with the support structure 10.

Die Anbindungsbleche 4 sind biegeweich und erlauben eine gewisse Relativbewegung zwischen den beiden Anbindungspunkten 6 eines Anbindungsbleches 4. Kommt es zu einer entsprechenden Relativbewegung, verformen sich die Anbindungsbleche 4 elastisch. Es können so Spannungsspitzen an der Verbindungsstelle zwischen Komponententräger 1 und Tragstruktur 10, wie sie bei einer starren Verbindung gemäß dem Stand der Technik regelmäßig auftreten, abgefangen werden. Der Komponententräger 1 ist zu einem gewissen Grad von der Tragstruktur 10 entkoppelt.The connection plates 4 are bendable and allow a certain relative movement between the two attachment points 6 of a connection plate 4. If there is a corresponding relative movement, the attachment plates 4 deform elastically. It can thus be trapped voltage spikes at the junction between the component carrier 1 and support structure 10, as they occur regularly in a rigid connection according to the prior art. The component carrier 1 is decoupled to a certain degree from the support structure 10.
